Modeling Lithographic Quantum Dots And Donors For Quantum Computation And Simulation, Mitchell Ian Brickson Dec 2023

Modeling Lithographic Quantum Dots And Donors For Quantum Computation And Simulation, Mitchell Ian Brickson

Physics & Astronomy ETDs

Our first focus is on few-hole quantum dots in germanium. We use discontinous Galerkin methods to discretize and solve the equations of a highly detailed k·p model that describes these systems, enabling a better understanding of experimental magnetospectroscopy results. We confirm the expected anisotropy of single-hole g-factors and describe mechanisms by which different orbital states have different g-factors. Building on this, we show that the g-factors in Ge holes are suciently sensitive to details of the device electrostatics that magnetospectroscopy data can be used to make a prediction of the underlying confinement potential. The second focus is on designing quantum …


Strategies To Improve Nonprofit Governance To Increase Donations, Charmaine Nicola Williams Tate Jan 2023

Strategies To Improve Nonprofit Governance To Increase Donations, Charmaine Nicola Williams Tate

Walden Dissertations and Doctoral Studies

AbstractThe leaders of nonprofit organizations rely on donors to achieve the organization’s mission, and governance practices are a key contributor to donor confidence and positive donor behavior. Some nonprofit leaders lack effective strategies to improve governance processes and encourage donor confidence to increase donations. Grounded in resource dependence theory, the purpose of this qualitative single case study was to explore strategies that nonprofit leaders use to improve governance processes and encourage donor confidence to increase levels of donations. The participants comprised four senior executive members of a donor-amalgamation nonprofit organization in the Midwestern United States. Data were collected from semistructured …
